       * properties:
       *   (Session对象未对外暴露任何属性字段, 所有访问通过下面的getter方法进行)
       * methods:
       *   type()     - String, 返回会话类型,"C2C"表示与好友私聊，"GROUP"表示群聊
       *   id()       - String, 返回会话ID
       *   name()     - String, 返回会话标题(如C2C类型中为对方的昵称,暂不支持)
       *   icon()     - String, 返回会话图标(对C2C类型中为对方的头像URL，暂不支持)
       *   unread()           - Integer, 返回会话未读条数
       *   time()     - Integer, 返回会话最后活跃时间, 为unix timestamp
       *   curMaxMsgSeq() - Integer, 返回会话最大消息序列号
